Grassroots innovator from Karnataka popular as ‘tamarind maniac’ selected for Padma Shri for Year 2022
Shri Abdul Khader Nadakattin, a serial grassroots innovator from Dharwad, Karnataka, is amongst the 107 Padma Shri awardees announced for the year 2022 in the Others  category.
Shri Abdul Khader Nadakattin is a serial innovator, and his prominent innovations include a device to separate tamarind seeds, ploughing blade manufacturing machine, Seed cum fertilizer drill, Water-heating boiler, an Automatic sugarcane sowing driller, and a wheel tiller. All his innovations demonstrate principles of sustainability, cost-effectiveness, eco-friendliness, and most importantly a, social acceptance. His in-depth knowledge of agro-climatic conditions and soil characteristics has made him an inspiration to other farmers in the country.
His first innovation was a “A Water Alarm,” which was his personalized attempt to solve his own nature of sleeping till late in the mornings. He tied a thin rope at the end of the key of the alarm in such a way that when the key unwound itself, the string tied to the key got wound. The string was in turn tied to a bottle filled with water, when the key was completely unwound, the bottle would tilt, and the water would fall on his face. Later he developed agri-technologies and implements which addressed a variety of needs for the local people while maintaining relevance with modern agriculture.
Supported by National Innovation Foundation  – India, an autonomous body of the Department of Science and Technology , Government of India Shri Abdul Khader Nadakattin was conferred with a Lifetime Achievement Award in 2015 during NIF’s 8th National Grassroots Innovation and Outstanding Traditional Knowledge Awards by the then Hon’ble President of India Shri Pranab Mukherjee. True to his grassroots spirit and as a mark of respect for the award, he chose to walk barefoot and hence came to be known as the country’s “barefoot scientist”.
Owing to his portfolio of innovations related to tamarind, people started calling him "hunase huccha", which means tamarind maniac. It started with his success in growing tamarind with scarce but alkaline water and further graduated with experiments like the technique for harvesting tamarind from the tree and also the highly accepted machine to separate tamarind seeds. This inspired him to develop a machine for slicing tamarind. In furtherance of success with tamarind, he came up with innovations to address agriculture operations like deep ploughing, sowing of seeds, and also fuel-efficient water heating boiler.
For several years in a row, the grassroots innovators are being recognized at different categories of the Padma awards, one of the highest civilian awards of India, which are given in various disciplines -- literature and education, arts, science and engineering, trade and industry, civil services, public affairs, sports, and medicine and inspiring the generation to innovate further!
